The Future of Solar Power

Scientists from Stanford has developed a nanostructure wiring that allows more light to be aborbed increasing its efficiency by approximately 20 to 22 percent. The nanostructure is composed of silicon nanopillars to reflect light away from the wires and into the solar cells. It is a semiconductor in between two metals that carries the generated electricity when these metals are sunlit. The nanopillars were used to increase the amount of light reaching the silicon in which the silicon were coated with a 16-nanometer-thick film of gold to let tight through."Solar cells are typically shaded by metal wires that cover five to 10 percent of the top surface," Narasimhan said. "In our best design, nearly two-thirds of the surface can be covered with metal, yet the reflection loss is only three percent. Having that much metal could increase conductivity and make the cell far more efficient at converting light to electricity."Want to know more about this awesome device? Follow this Link!
